I'll tell you what's unusual about this CD 202 embossed K ; it's in fantastic condition. Every time I pick up a K transposition, it seems it has serious problems. The inner skirts are always banged up or there are chips and dings everywhere. Not so with this insulator. Not only is it in NEAR perfect condition there is a bean size pot stone in the dome. I'm asking $50 plus actual shipping cost for this fine looking one piece transposition.
